Kho rear qhov rais cua kub tus kheej ob txhais tes

Tam sim no txhua txhua ib lub tsheb yog txawm peem rau nrog ib tug rhaub nyob rau hauv lub rear qhov rais. Dig muag, nws zoo li ib tug nyias xov, uas yog vim li cas cov neeg tsav tsheb hu lawv "threads ntawm lub rhaub." Qhov cuab yeej no yog tsim los zoo tshem tawm te los ntawm cov iav nto, li no tiv thaiv qhov tshwm sim ntawm cov dej khov ua kiav txhab txij ntawd lawm. Yog hais tias lub rhaub yog cov, nws yuav tsum tau significantly cuam tshuam visibility. Rime yuav kiag li npog qhov chaw ntawm cov iav, tsim ib qho xwm ceev qhov teeb meem no. Yog li ntawd, qhov no mechanism yuav tsum nco ntsoov yuav nyob rau hauv kev ua hauj lwm kev txiav txim. Zoo, yog koj yuav tau kho lub rhuab nram qab qhov rais, ces qhov no tsab xov xwm - rau koj.

Ua ntej peb yuav los mus txiav txim ntawm qhov chaw uas cov threads raug puas. Qhov no yuav ua tau siv ib tug voltmeter. Thaum lub voltage ntawm ob rhaub nyob ntawm tej yuav tsum tau 11 volts.

Tam sim no koj yuav tsum npaj qhov tsim nyog cov cuab yeej. Nyob rau hauv thiaj li yuav kom kho vaj tse qualitatively tsheb rear qhov rais defogger, peb yuav tsum tau sulfuric acid, piece ntawm ib tug tooj liab raj nrog ib lub cheeb ntawm 7-8 millimeters, tooj liab sulfate thiab sawb loj 30h0.5 millimeter cov ntaub so ntswg.

Qhov kawg ntawm tus raj winding ntawm tej khaub ncaws. Winding xav tau ib nrab xwb nws dav, kom tau ib tug tsi ntawm txhuam. Tam sim no muab tso rau ib tug xov rau hauv cov ntaub thiaj li hais tias cov tom kawg tsis so. Nyob rau hauv lub tom ntej no theem ntawm kev kho rear qhov rais defogger davhlau ya nyob twg yog nrog los ntawm ntsha chaw tsim tshuaj paus. Yuav tau noj cov iav sau ib nrab ntawm nws volume ntawm dej, ces ncuav ob peb teaspoons ntawm tooj liab sulfate. Cov uas ua sib tov twb kom huv si do, thiab ntxiv ib qho kev daws ntawm concentrated sulfuric acid (100 milliliters kwv yees li ½ teaspoon).

Tam sim no peb txoj kev sib terminals mus rau lub luj; "+" Roj teeb yog kev cob cog rua rau lub raj. Zoo electrode dipped nyob rau hauv cov tshuaj thiab cov txheej txheem lawv qhov chaw kis filaments. Voltage uas yuav kis tau los ntawm qhov tam sim no hloov tooj liab ion, whereby lub filaments yog rhuab. Yog hais tias lub scale ntawm kev puas tsuaj yog me me, ces tom qab 5 feeb, rhuab nram qab screen kho yuav ua kom tiav, thiab lub tsev yuav tag nrho ua hauj lwm. Yog hais tias nws tsis, nws txhais tau tias threads puas tiag. Nyob rau hauv cov ntaub ntawv no, lub ob txhais tes coj lub soldering thiab ua rau lawv feem coated nrog cov tshuaj. Rau ntawm no theem, peb yuav tsum tau solder lub jumper ntawm ib tug nyias hlau. Tsis tas li ntawd tsis txhob hnov qab tias cov kua nrog sulfuric acid yog heev txaus ntshai rau cov ntaub rau khaub ncaws, ces siv ceev faj.

Yog hais tias koj tseem tsis tau ntseeg nyob rau hauv lawv lub peev xwm, koj yuav tau sim kho lub rear qhov rais defogger lwm yam, cuam sai thiab yooj yim txoj kev. Rau no peb yuav tsum tau ib tug kho khoom siv Ua li cas Deal. Nws yog tsim rau tej kev ua hauj lwm. Nplaum yuav tsim nyob rau hauv lub khob nto ib conductive txheej uas muaj tib lub hluav taws xob kuj raws li lub yarns lawv tus kheej.

Whichever kho txoj kev uas koj siv, tag nrho cov tib nyob rau hauv ob leeg, lub rear qhov rais rhaub yog kho. Qhov txawv tsuas nyob rau hauv lub sij hawm thiab kim ua hauj lwm.
